JOHN EMERSON FEATHERSTQN, OF VALLEY CTY, NORTH AUTGMOBILE TUBE AND TERE To all whom it may commen s Be it known that I, JOHN E., FRAN-mw sToN,-a citizen of the United States, and a resident of Valley City, in 'rhe couniy of Barnes and State of North Dakota', have in: vented a new and useful mprovement in Automobile Tube and Tire Signalsg of which the following is a Specification.

lliy invention relates to automobile Lube and tire signals, my more particular purpose being to povide a combination of u tube oz' iuiating automobile tires, and e valve im retaining the air after the leiter has been' pumped into the tire, together Willi means for producing a Signal Wlleneveil @be "tire is deflated While in use.

My invention comprehends more especially an'automobile Wheel )rim carrying e tir-e :mel having a tube extending raflially thx-:magix the rim, and e plunger fitted air-tight Wil-bin Said tube and carrying a wzlve fm' reeining liry in the ie, the plungeim being mevilble and controllable by (leaien el? che the purpose of actuating die signa-l.

2. A device of the character described, comprising a pneumatic tire, a wheel rim for carrying said tire, a tube extending radially through said wheelirim and .communicating with vthe 'interiorbf said tire, a plunger movable relatively to said tube and extending through the same, means for rendering said plunger air-tight relatively to said tube, a valve carried by said plunger for preventin retrogression of air when said air is force under pressure through said plunger into said tire, and signaling mechanism controllable by movements of is deflated and is rolli 'wheelrim when said tire is deflated and saidv 'plunger is brought near the ground during the rotation of the wheel, a valve/mounted upon said tubular plunger 4for preventing retrogression of air therethrough from said tire, a firing pin carried' by said tubular plunger, and means for holding a cartridge adjacent to said firing pin.

4. A device of the character described, comprising a wheel rim, a tire member carried thereby and normally inflated, a tubue lar plunger carried by said wheel rim and communicatin pose of infiating the same'+ a valve carried bysaid plunger for the purpose of prevent- 'ing retrogression of air from said tire member, said plunger being movable relatively to said Wheel rim Whe 'said tire member n upon the ground, and means controllable by movements of said plunger for actuating an alarm.
